Someone who doesn't appreciate all of the good music from all different genres for it's musicalness and musicality , but instead only likes one genre only and latches onto that one genre in it's entirety , it's look , it's clothing , it's fashion , it's lifestyle , all in a feeble attempt to be seen as cool and to act like a snob and pretend they are better than someone else who's not into their narrow , shallow , narcissistic , superficial , artificial coolness.

punk idiot: I'm like so punk , I act punk , I dress punk , I look so fucking punk , and all I listen to is punk.

metal idiot: I'm like so fucking metal , I act metal , I dress dress metal , I look so metal and badass , and all I listen to is metal.

normal person: You guys are posers.Good music and bad music exists in all genres of music and you need to listen to more than just one genre of music. Besides if all you listen to is just one genre then you must be suffering from the delusion that everything in that one genre constitutes GOOD MUSIC which is impossible since every genre has it's share of good music and bad music regardless of how simple or complex the music is.You guys just don't want to have to think too hard (aw is thinking too hard?) and so you take the easy way out and latch onto one thing hard.Then you adopt the look and the fashion and the hairdo and the lifestyle and "pose" as that image and think that makes you all cool and badass.It doesn't.You're lame.Posers!

Alright, where shall I start? Hmm.. A poser is someone who tries to fit in with a certain crowds, or masks who they really are to fit in.
You shouldn't have to do this to be accepted.
I mean, don't say you skateboard when one, you have no idea how to in the first place, and two, you could get yourself into a conversation about skateboarding where you don't know what the hell you're even talking about.
I mean, why should it matter what crowd you fit into?
If you're naturally a scene kid, go ahead, keep on being scene. We like it.
If you're naturally a prep, be a prep. Who gives a flying leap?
If you're a prep, and you like a scene kid and you feel you have to change yourself so that they'll notice you, don't. They won't like it, and you won't like it. Besides, who knows? They may just like you for the way you are.

Ohh, and just because someone listens to Good Charlotte, doesn't mean that they're a poser. They just like them.

If a situation arises where you hear that someone likes Good Charlotte, talk to them. See if they like any other bands. Who knows? They could like A Cursive Memory or The Dreseden Dolls just as much.

..BUT, if they say, "Ohh yeah, Good Charlotte is like, so punk.", you have my permission to kick the shit out of them.

Good Charlotte is not punk, mmkay pumpkins?
but just because some people like them doesn't mean they're posers.

This is a word used for people who act, dress, talk like people they aren't. It's a label for a person who is pretending they are someone totally different. It's most often used to describe people calling themsevles "punk."

Lil Johnny Bob is such a f*cking poser. He gets liberty spikes and puts safety pins in everything he owns and now automatically assumes he's a punk rocker child?! Bullsh*t!

well, a poser is someone who says that they are a punk because they have a cky cd and a ramones shirt, and dont even like the cd, and have never heard a song by the ramones,clash, sex pistols, or real punk music. most have liberty spiked hair or a "fohawk", and listen to Good Charlotte, Simple Plan, and Avril Lavinge, or songs about relationships(and ending them, and how bad it hurts)

dude, im such a punk!!! i got the Good Charlotte Dvd and a sex pistols shirt. dude, im so fuckin cool

A word popularized by the teenagers of this generation. It is used to describe someone who is "biting off" another person, and one who tries to fit in with a group. Honestly, no one even gives a shit about who are "posers" and who aren't. In today's logic, any newcomer is a poser, or anyone who decides to wear something else or listen to something else is a poser. The word is used to bash those who try new things regardless of reason for doing so, and it's one of the most overused words by teenagers. It is mostly used by people who have no self-esteem and resort to talking down to other people or friends to satisfy themselves. Seriously people, fuck off already.

Guy #1: Dude, stop wearing LRG, you're such a fucking poser!
Guy #2: Whateva, I do what I want!

1.People who pretend to be something they're not because they think it makes them realy cool when in actual fact it makes them look like desperate wannabe's who can't get friends any other way (which is what they are).

2.Also when people pretend to like, for instance, a band when actauly they just think the lead singer is 'hot' as opposed to actualy liking the music.

Poser: OMG i sooooooooooo love mcr! They are like my favourite band.
Non-poser: Realy? same, i realy like their music. My favourite song is probably 'You know what they do to guys like u in prison'. Whats yours?
Poser: ummm...uh...i dunno but Gerard Way is waaaaay hot!

(btw im not saying mcr are not hot im just saying that thats the ONLY reason the posers will like the band, because they think they're hot.)
